Power Windows - Tailgate: Description

Tailgate window system consists of a 12 volt reversible direction motor, that is protected by an internal circuit breaker which may require 1 to 3 minutes to reset. Window is controlled by a jackscrew type regulator. Window is operated by an instrument panel switch with the ignition switch at "ON" position, or an external key switch located in the tailgate door. A cut-out switch prevents operation of the window by either switch when tailgate is open. Window will retract into tailgate door. Circuit is protected by a 30-ampere circuit breaker located at fuse block.
